96 Deville with 75000 miles. Occasionaly when I start the engine it pops instead of starting. At about 1/3 throttle slight hesitation and runs a little rough. It accelerates great at full throttle. Spark Plugs?? Thanks in advance for any suggestions.

could be....but at 75K miles they should be still good.

Any DTC codes? Push OFF and WARMER on your dash for a few seconds, write down codes and let us know.

suspects include plugs, wires, dirty thottle body, fuel rail/injectors, fuel filter.....all just a guess and I may be doing a disservice to you by listing them.
